I played an Altus flute for a short while when I had one home on trial. I think it was the 1107 model. It was a very close call, but I ended up purchasing a Muramatsu. In my opinion, the Altus is a great flute - nicely built, and the keywork felt great. I would recommend that you take a serious look at it.
I hope this humble opinion helps you.
